Abstract: 
Transport experiments in the system Cr/Nb/O yielded the compound (Cr, Nb)12O29 as crystalline green needles. The lattice parameters of the monoclinic cell are a = 31.162(8) angstrom, b = 3.8324(6) angstrom, c = 20.579(6) angstrom, beta = 113.22(3)-degrees. (Cr, Nb)12O29 is isotypic with monoclinic Nb12O29 as shown by Guinier diagrams and high resolution transmission electron microscopy. Characteristic structural building elements are [3x4]-blocks which are columnar sections from the ReO3 structure. In the real structure one finds numerous defects. Under the influence of the electron beam we observed reversible changes of contrast which indicates that the positions of the M-particles (M = Cr, Nb) have shifted.
